a DIE argument instead of an info_ptr.

Do not add DIEs to the hash table if we aren't going to look them
up.

arguments.

abbrev_obstack.
(dwarf2_empty_abbrev_table): Just call obstack_free.

rearrange members for packing. Replace spec_attr with spec_offset.
(load_partial_dies): Only follow structures for C++.
(load_partial_die): Use memset. Save specification attributes
only as offsets.
(fixup_partial_die): Adjust to use spec_offset.
2004-02-21 Daniel Jacobowitz <drow@mvista.com>
